Chastity and orgasm denial discussion

“Body Scanner Discoveries This Week –** … . . And while it isn’t prohibited, a passenger wearing a chastity belt alarmed the body scanner at one of our checkpoints. I’m sure you can imagine where an undergarment such as this might be a problem at a security checkpoint. Especially if there is no key.” Does anyone have actual experience with going through airport security with a device locked on? Putting aside the humiliation factor, I am not sure it would be such a big deal to just ask for a pat-down instead of the metal detector and let TSA know you’re wearing a chastity cage.
